7 '0 all whomtz't may concern:

Be it known that I, AnoLPH 'SGHWER, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a certain new and useful Improvement in Phonographs, of whichthe following is a specification.-

This invention relates to improvements in phonographs. v i

One of the features of the invention has reference to a disk recordmechanism and a cylinder record mechanism, eachof which is complete initself and independent of the other, a driving mechanism andmeans forconnecting the driving mechanism with either the disk record mechanismor the cyl-. inder record mechanism.

Another feature has reference to the mounting of the disk recordmechanism, the cylinder record mechanism and the driving mechanism onamovable base or support .so that said mechanisms ma be quickly andconveniently exposed for a justment 'orreair. P Anotherfeaturehasreference to the mannor of starting and stopping the drivingmechanism, re ulating the speed and shift-- ing from the isk recordmechanism to the cylinder record mechanism or vice versa.-

The principal objects of the invention are to provide for almostinstantaneously changing from one record mechanism to another, toperfectly control and regulate the speed at will, to start and stop themechanism when desired, and to arrange the various mechanisms so thatthey are quickly accessible for adjustment or repair.

The invention also relates to certain details of construction which willbe hereinafter described and claimed, reference being had to theaccompanying drawingsdn which a preferred adaptation of the machine isshown.

Fig. 2, is avertlcal transverse sectlon through the upperportion of the box of themachine with a front elevation of the various mechanisms attached thesame. Fig. 3, is a fragmentary perspective View to illustrate the'toggle clutch operating mechanism. and one member of one of theclutches. Fig. l, is a fragmentary horizontal section'through the boxwith a bottom view of the driviljg mecha-v nism. Fig. 5, is afragmentary vertical sectlon through the box on line 5 5- Fig. 4, tolllustrate the startin and stopping friction brake mechanism. ig. 6 is afragmentary section through the box on line 6 6 Fig. 4, to-

illustrate the ratchet and dog locking device of the spring drivingmechanism. Fig. 7, is

an enlarged fragmentary section through one of the clutch mechanisms.Fig. ,8, is a vertical longitudinal sectionthrough the box, the drivingmechanism being omitted.

In referring to the of the improved machine illustrated in the meralsdesignate like parts.

- The box 1 as shown has a lower sounding compartment 2 and an upperinclosing compartment 3 for the driving mechanism. The box top iscomposed of a fixed or stationary rear portion 4 and a movable frontportion 5 which is hinged at its rear edge to the front edge of thefixed rear portion 4; said movable front portion forming a cover' anismand the other for the cylinder record mechanism are absolutelyindependent of each other and are supported from the fixed rear portion4 of the top of the box. Said reproducing mechanisms are adapted to bepreferred adaptation accompanying drawings in detail like nuswungmanually by the operator into" and out of operating position withreference to the records.

The disk record mechanism consists of' a vertical shaft 6 journaled in adeppndin bracket 7 attached to and dependin eneat 1 the cover 5 andhaving its upper en rojecting l'oos y through an opening in t e saidcover and a horizontal support or turn table 8 fixed to the upperproyecting end of the shaft 6 upon which the disk records are adapted tobe placed in the usual manner.

. The reproducing mechanism for the'disk record mechanism includeerasound conducting tube 9 which is supported from the fixed rear portion 4and has the usual goose neck l0 and a sound box ll arranged at theforward terminal of said goose neck which can ries the needle 12.

The cyllnder record mechanism is mounted on the cover at one side of thedisk rec- 0rd mechanism and comprises a frame 13, a cylinder recordsupporting mandrel 14 journaled in said frame, a screw bar 15 forfeeding the reproducer goose neck along the record an mandrel,.asmall'pinion 19 mounted on said shaft. an intermediate shaft, 20, acentrally mounted spur gear wheel 21 on said shaft 20 which meshes withthe pinion 19, two spur gear wheels 22 and 23 also mounted on the shaft20 on opposite sides of the wheel-21, a slide shaft 2% connected to thefeed bar 15 and two gear wheels 25 and 26 on said slide shaftadaptedto-mesh respec tively with the gear wheels 22 and 2.3 see Fig.1.7 Y i he slide shaft 2 1 has anenlarged knurled head 27 at its outer endwhich is adapted to be grasped by the operator to slide a movable clutchmember 27* attached to ,the inner end of the slide shaft. 24 intoclutching engagement with either one of two fixed clutch members 27" and27 which are respectively attached to the gear wheels 25 and 26 as shownin Fig. 1. The gear wheels 25 and 26 are always in mesh with the gearwheels 22 and 23 and are loosely mounted on the slide shaft 24 so as torotate independently thereof except when clutched thereto by the movableclutch member 27 In Fig. 1 the movable clutch member is shown inclutching engagement with the fixed clutch member 27 attachcd to thegear wheel 25 and outbf clutching engagement with the fixed clutchmember Q'F'attached to the gear wheel 26. The purpose of this mechanismis to enable the ratio of speed between the feed 'bar 15 and themandrel.

1 1 to be varied or changed so that different styles of cylinder recordsmay be played on the same machine. The cylinder record reproducingmeehw;

nism is similar to the disk record reproducing mechanism; being locatedon one side thereof and it consists of a sound conducting tube 28supported from the fixed rear portion 4;,- a goose neck tube29 .ivotallyattached to the tube 28, a semi box 30 attached to the forward terminalof the goose neck tube 29 and a needle 31 carried by said i sound box.

The driving mechanism in the adaptation illustrated is-of the springoperatedtype.

Referring to Figs. 2 1 and 5, a spiral spring 32 is'incased within thetwo parts 33 and 3st of a two member cylindrical housing and is adaptedto be wound up or placed under tension by a winding handle 35 (afragment of the stem of said handle being shown in Fig. at) which isdetachably fitted on the end of a shaft 36 journaled in hearings in abracket 37 depending from the cover 5.

The shaft 36 is provided with a ratchet wheel 37 and a pivotal lockingdog 38 is arranged-to engage the teeth of the ratchet wheel and therebyprevent the shaft 36 turning in the reverse direction or in a directionto unwind the spring. see Fig. (3.

A spur gear wheel 39 is mounted on the shaft 36 which meshes with a spurgear wheel 10 mounted on a short projecting;

shaft 11 extending from the outer member 34 of the housing. The housingmember 3-1 is also provided at its outer end with a large spur gearwheel as which meshes with a small pinion 43 mounted on an intermediateshaft 14;, see Fig. 4;

At the opposite end of the intermediate shaft is arranged a spur gearwheel, 15 which meshes with a spur gear wheel t6 mounted on one member417 of a clutch which is arranged on the driving shaft for the cylinderrecord mechanism.

The clutch member 17 is loose on the shaft 48 being free .to rotateindependently thereon but is held against longitudinal movement thereonby one of the two frame members 4-9 and 50 in which the driving shaft 18is journaled. The other or opposite member 51 of the clutch is alsomounted on the driving shaft but is nnrotatably fastened thereon by apin extending transversely from the shaft and projecting in alongitudinal slot in the clutch member 51 as shown in Fig. 3, whichpermits it to be shifted into and out of-clutching eugagement with theother clutch member.

The driving shaft 4:8 for the cylinder record mechanism is connected tothe shaft 18 extending from the cylinder mandrel by a belt 5% whichencirclcspulleys and 56 mounted respectively on the driving shaft 18 andshaft 18 shown'in Fig. 2.

A driving shaft 57 for the disk record mechanism is also mounted beneaththe cover 5 shown in Fig. 1, and has a hovel gear, wheel 58 at one endwhich meshes with a bevel gear wheel 59 on the vertical shaft u.

A clutch similar to the clutch mounted on the driving shaft 48 islikewise mounted on the driving shaft 57 for the disk record mechanismand consists of two members GO and '61; the member (10 being slidablyhut uurotatably secured thereon and the other member til looselysurrounding the shaft but held from longitudinal movement thereon. Themember (31 is rotatable independently of the shaft and carries a pinion62 which meshes with the spur gear wheel on the intermediate shaft 44.The slidable members of the two clutches are connected to a singleclutch shifting mechanism for simultaneous operation. i

F or an understanding of the principal portion of the clutch shiftingmechanism reference is to be had to Fig. 3. r A rock shaft 63 isjournaled in brackets 64 and carries a crank arm 65 provided with abifurcated end 66 which loosely engages in a groove 67 in the clutchmember 51 and a bell crank68 which is connected at one end to the clutchmember of the clutch controlling the operation of the disk record.

mechanism and at the opposite end to a toggle arm '69 extending from therock 'shatt.

, From this construction it will be noted that v by the bell crank andtoggle, thereby bringby rocking the shaft 63, the slidable clutch member51 will be moved in one direction by the crankarm while the other clutchmember is shifted in the opposite direction ing one clutch intoclutching engagement and simultaneously therewith disengaging the otherclutch.

The shaft 63 is rocked by meansof a turn button 70 arranged on the topof the cover 5 and having a depending stem 71 and a transverse arm 72 atthe lower end of said depending stem which is provided with an opening(not shown) through which one end of ably fits. The arm 72 is balancedyieldingly on said rod 73 between two springs 74 and 75 which are heldin place on the rod by two' separated washers 76 and 77 and the opposite end of said rod 73 is pivoted to a crank 78 extending from therockshaft 63. The purpose of the springs 74 and 7 5 are to provide acspringtension on the rod in either drrectiun it is moved and thereby force theslidabl'e clutch member of the clutch that is being engaged intoclutching position as soon as it registers with its opposed clutchmember.

The speed of the machine is cont-rolled by a governor 79 of the ballspring type and said governor is regulated and adjusted to vary thespeed by a turn button BOpro ecting from the top of the cover and havinga stem 81 extendin through an opening in the cover; said stem beingprovided at its lower end with a cam 82 which is connected to thegovernor is a connecting rod 83.

the mac ine is started and stopped by the operator ttirnin athird button84 mounted on the cover which controls a friction brake 85 ada ted to beenga ed with or dlsengaged i i-om a wheel 86 s own in Fig. 5.

The brake shoe 85 is pivotall mounted on one end of a lever arm 87 whichis pivoted at an intermediate point to a bracket 88 and at its 0 positeend to the lower terminal of a verticairod 89.

loosely through aniopning 90 inthe cover 5 and into a recess in thebutton 84 and has a transversely extending portion 91 at its upper endwhich slidabl fitsfthrough .a cam slot 92 in the side-0 the button 84;.By

turning the button 84 in one, direction, the

rod 89 is lowered applying the brake and by turning it in the oppositedirection the rod is raised disengaging thebrake.

A -spring 93 is mounted on the rod 89. beingheldthereon by a washer 94;the tendency ofsaid spring beingjto press. the rod 'downwardin adirection to apply the brake.

The operation of this improved machine is as" followsg -The spring ofthe driving mechanism'having been wound up by turning the-handle. 35 anda {record or records having been placed on one-or both the turn table 8and the mandrel 14; the machine is started by turningthe button .84; ina direction to release the brake, the clutch shifting mechanism is movedto connect either the disk or the cylinder record mechanism with the drving mechanism by turnin the button'70 in the desired direction,"an thespeed is regulated by turning the 'button 80. In this improved machinethe-- disk and cylinder record mechanisms are entirely independent ofeach other and ar arranged so that they are operated from a singledriving mechanism. 7

It will be understood that the foregoing mechanisms may be altered orvaried within the scope of the following claims without departing frommy invention.
